手头使用的开发板是BPI 的M2S，芯片是A311D，使用的自己的仓库 https://github.com/zjd1988/timvx_engine.git 生成的可执行程序，从dmesg看，驱动已经加载了，但是依然提示找不到设备，其他依赖的so从这个仓库获取的https://github.com/Amlogic-NN/AML_NN_SDK/tree/master/Linux/runtime_sharelib/DDK6487/A311D_0x88/lib64，这个报错是因为什么导致的呢？

@zjd1988 ,

你的Kernel驱动和UMD是配套的吗？

[zjd1988]

@sunshinemyson 这个UMD是指user mode driver吗，如何确认呢，是指libVSC.so这些库跟garlcore.ko是否配套吗？libVSC.so这些库确实不是板子镜像自带的，是从[https://github.com/Amlogic-NN/AML_NN_SDK](https://github.com/Amlogic-NN/AML_NN_SDK/ 这个链接下载的，因为bpi没有提供对应的so，也问了客服和技术支持，不知道如何使用npu

@zjd1988 ,

你的galcore.ko 是哪里拿到的呢？我也去其他途径问一下看有没有办法帮助你。

在vim3 pro开发板可以加载模型和推理
